yExtending' up fromthe loom sided and and other parts connected is the lay, carried rigidlysecured thereto, is'a stand 11 having an upper cylindrical portion 11-, see Fig'. 3. The upper cylindrical shaped portion 11' surrounds the head part of the magazine, and-has anopening 11'-therethrough at'the lower part thereof, see Fig.2, through which i the head of the bobbin passes-when a bobbin is discharged from the. magazine;- Atthe' central portion of the end 11' is a hub 11", through which extends the reduced end 12'" of a stud 12., The stud 12 is firmly secured in the-hub portion 11 by a nut 13 'onthe outer threaded end of said stud, and the inner. threaded 'end' of the stud l2ha's a washer, 1d thereon, and a nut 15.

Loosely mounted on' tlie swam is the hollow hub l6 ofthe magazinel From the l1ub' 16 extends a series of arms (Jr-spokes 16 carrying the outer ring 16' for the tips of the bobbins 9. The ring 16 has a series of radial notches 16, ineach of which is blade 17, see Fig. 3, having its inner bent end at the outer end th'ereo f. l

of the notch, and secured at its inner end b' az'screw 17-, Thes 'rin'g'17 acts'to yiel ingly hold-the tip 0 the bobbin within the sufiic-ientto' enable thoseskilled in the art to '"notch'es- 16 in thering 16" of-th'e magaunderstand the constructionand ope-ration zine. The head of each bobbin-9 is inserted class referred :to, "and a rotary magazine, and my improvements combined therewith,

ring .19 is connected with and carried by rods 20, which extend transversely between stance there are four bobbins in each group.

The reduced ends 20' of the rods 20 extend through the ring '16, and extend inwardly from said ring, and have secured on their ends a ring 21, preferably made out of sheet metal, which forms a surface over which the filling 9 from the bobbins 9 passes, see Fig. 3. The thread ring 21 has notches 21 on its periphery, see Fig. 2, in which notches the filling thread 9 from the bobbins 9 passes, and is wound around "and held, preferably by a clamping device consisting of a pin 22 extending loosely through the ring 21, and having a washer or enlarged end 22 on its outer end. A helically coiled expansion spring 23 encircles said pin 22, and bears at one end against a washer 22 on said pin, and at its other end against the threaded ring 21, and acts to yieldingly move outward said pin and the end 22 thereon, to yieldingly' hold the end of the filling thread between the end of said pin, and the ring 21. The head 22 is preferably slotted at 22', see Fig. 2,'so that the ends of the threads wound around the pin 22,

may be easily cut and removed, if. desired.

, The outer reduced end 16 of the hollow hub 16 of the magazine, has loosely mounted thereon the hub 24"of the worm gear 24, which gear meshes with and is driven by the worm 25, see Fig. 1. The worm 25 extends loosely within a suitable recess 11 in the cylindrical head 11, and is fast on the upper end of a vertically extending shaft 26. The

lower end of said shaft 26 extends loosely through a'bracket or bearing 27, attached to the loom side. The vertically moving shaft 26 has a square shaped portion 26 2 .5.

thereon, which moves longitudinally in the elongated hub 28 of a bevel pinion 28, see Fig. The hub 28' of the-bevel pinion 28 extends out from said pinion on its upper and lowerside, as shown-in Fig. 5, an

upper part of said hub is loosely mounted in a bearing 29 attached to the loom side,

and the lower part of said hub is loosely mounted in a bearing 30 attached to the loom side, see Fig. 5.

Upon the vertically extendin shaft 26 is secured a circular disk 26", wgich extends between the fork shaped end 31 of a lever 31, and has a hub-31 pivotally mounted on a stud 32 secured tothe loom side. There is an extension 31' on hub 31", to which is connected one end of a helically coiled contraction spring 33; the other end of said spring 33 is connected to an ear 34 on the loom side 1', see Fig. 1; said spring 33 acts to draw down the lever 31." A flexible connection or chain 35 is attached at one end to the lever 31, and passes over a guide sheave engagement of the forked end 31 of said lever with the disk 26 on the vertically moving upright shaft 26, raises and lowers said shaft, and also the worm 25 fast thereon, which meshes withthe worm gear 22 for rotating the magazine, in order to oscillate or rock the magazine according to the position of the change shuttle boxes. If preferred a separate attern surface may be used for operating t e lever 31.

The bevel pinion 28 meshes with and is driven by the toother portion 36' of the cylindrical bevel gear 36, see Fig. 5. The hub 36" of said cylindrical e'ar 36 is loosely mounted on a stud 37 on t e lower end of an upwardly extending arm 38' of a stand 38. The cylindrical gear 36 has thereon four notches 36*, see Fig. 4, in which is adapted to extend a projection 39 on a pawl 39. The hub 39 of said pawl 39 is loosely mounted on a stud 40 on the stand 38. The pawl 39 is adapted to be raised by a rod 41 connected at its lower end to said pawl, an at its upper end connected to the transferrer arm 42, see Fig. 1, when said transferrer arm 42 is operated to transfer a bobbin from the magazine. The pawl 39 has a side extension 39* thereon, which enga es with the end of a shield 43, to hold said shield in the position shown in Fig. 4. .The hub 43 of the shield 43 is in this instance loosely mounted on the elongated hub 36" of the cylindrical bevel ear 36. Extending downwardly from sai hub 43 of the shield 43, is an arm '43", the end of which has a cylindrical extension 43 thereon, see Fig. 5, in which is yieldingly held, by the helically coiled compression spring 44, a pin 45. The sprin actuated pin 45 extends out from its cylin rical holder to enga e the ratchet portion 36 on the cylindrica bevel gear 36, to move said gear one-fourth of its revolution, when the pawl 39 is raised by the transferrer nected with a bolt 47, which is adjustably secured in an elongated slot 48 in one end of a lever 48, which has its hub 48" pivotally mounted on a pin 49 on a bracket 50 on the loom side. The lever 49 has a in 51v thereon, on which is mounted a re 1" 52, which engages with the periphery of a cam 53 fast on the bottom shaft 10.

A helically coiled contracaion spring .54 is attached at one end to said ever 49, and at its other end to a pin 55 on the loom side 1, and acts to hold the roll 52 in engagement with said cam 53 after the shield portion is disengaged from the pawl 39, in order to revolve the magazine.

It will be understood that the details of construction of my improvements may be varied if desired.
